#1417 Anonymous Inner Class: ParseException: Encountered " "." ". ""

[Christopher Jung]

I get the following error when I use anonymous inner classes like this:

70  @Override
71  public void doCreateContext(final Context context)
72  {
73      executeInLocalView(new SessionExecutionBody()
74      {
75          @Override
76          public void executeWithoutResult()
77          {
78              HGCmsElementSyncAction.super.doCreateContext(context);
79          }
80      });
81  }

[Andreas Dangel]

Thanks for reporting this bug.
This bug has already been fixed with PMD 5.0.5 - see [#1107].

Please upgrade to at least PMD 5.0.5.

Hi Andreas,

thanks for that advice! I have upgraded to PMD 5.4.0 but now I get this parser error for another class:

The class looks like this:

106             final String value = HGXLIFFTypeConfiguration.this.attributes.get(key);
107             
108             String result = key;
109             if(StringUtils.isNotEmpty(value))
110             {
111                 result = result.concat(":").concat(value);

113             return result;
114         }
115     })));
116 }

Thanks for testing.

I've created a new bug for this new parse error -> [#1429]

As a workaround, you can remove the cast ((Set<String>)) as this is unnecessary anyway in this case.
